Hearing the words “colon cancer” can be frightening. Even reading about it may cause anxiety. If you’re worried about symptoms, test results, or a family member’s diagnosis, you’re not alone. Many people feel overwhelmed at first.
Let’s break this down simply.
This guide explains colon cancer in clear, simple terms. It covers what it is, how it’s diagnosed, common symptoms, risk factors, and when it’s important to see a Colorectal cancer surgeon in OMR for expert guidance. The goal is not to alarm you—but to help you understand your options and feel more informed.
What Is Colon Cancer?
The colon is part of your large intestine. Its main job is to absorb water and help move waste out of the body.
Colon cancer begins when cells in the lining of the colon start growing in an abnormal way. This growth often starts as a small lump called a polyp. Most polyps are harmless. But over time, some may turn cancerous.
You might be wondering: Does colon cancer happen suddenly?
In most cases, no. Colon cancer usually develops slowly over several years. This is why screening and early evaluation—often guided by a Colorectal cancer surgeon in OMR—can play an important role in timely care.

Stages of Colon Cancer
Doctors describe colon cancer in stages. Staging helps guide treatment decisions and gives a clearer picture of how far the disease has progressed.
Stage 0 (Very Early Stage)
- Cancer cells are only in the inner lining of the colon
- Often found during routine screening
- Treatment may involve removing the affected area
Stage I
- Cancer has grown slightly deeper into the colon wall
- It has not spread outside the colon
Stage II
- Cancer has grown through the colon wall
- Nearby organs may be involved, but lymph nodes are not
Stage III
- Cancer has spread to nearby lymph nodes
- It has not spread to distant organs
Stage IV
- Cancer has spread to distant organs such as the liver or lungs
This often causes anxiety, but it’s important to know that treatment options exist at every stage. A Colorectal cancer surgeon in OMR usually works with a wider medical team to recommend care based on the stage and a patient’s overall health.
How Is Colon Cancer Diagnosed?
Diagnosis usually involves more than one test. Doctors do not rely on symptoms alone.
Common Diagnostic Tests
Colonoscopy
A thin, flexible tube with a camera is used to view the inside of the colon. Polyps or abnormal areas can be removed or biopsied during the same procedure. This test is commonly advised before meeting a Colon cancer surgeon in OMR for further planning.
Biopsy
A small tissue sample is examined under a microscope to confirm whether cancer cells are present.
Imaging Tests
CT scans or MRI scans may be used to understand the extent of the disease.
Blood Tests
Blood tests cannot diagnose colon cancer, but they may help assess overall health or monitor treatment response.
If you’re worried about these tests, it helps to know that most are routine, safe, and done to gather accurate information—not to rush into treatment.
Symptoms of Colon Cancer
Symptoms can vary widely. Some people have no symptoms in the early stages. Others notice subtle changes that are easy to ignore.
Common symptoms may include:
- Changes in bowel habits (diarrhea or constipation lasting more than a few weeks)
- Blood in the stool
- Ongoing abdominal discomfort or bloating
- Feeling that the bowel does not empty completely
- Unexplained weight loss
- Fatigue or weakness
You might be wondering: Do these symptoms always mean cancer?
No. These symptoms can also be caused by common conditions like piles, infections, or irritable bowel issues. Still, persistent symptoms should always be checked—often starting with evaluation at a colorectal clinic in OMR where further tests can be arranged if needed.
Causes of Colon Cancer
There is no single cause of colon cancer. It usually develops due to a combination of factors over time.
Some contributing factors may include:
- Genetic changes in colon cells
- Long-standing inflammation in the colon
- Lifestyle habits that affect gut health
Often, people ask, “Did I do something wrong?”
In most cases, the answer is no. Many people diagnosed with colon cancer had no clear warning signs or known causes, which is why timely consultation with a Colorectal Cancer Surgeon in OMR
Risk Factors You Should Know About
Certain factors may increase the risk of colon cancer, though having one or more does not mean you will develop it.
Common Risk Factors
- Age over 45–50 years
- Family history of colon cancer or polyps
- Diet low in fiber and high in processed foods
- Lack of physical activity
- Smoking or long-term alcohol use
- Obesity
- Long-standing bowel conditions like ulcerative colitis
If you’re worried because colon cancer runs in your family, discussing screening options with a Colorectal cancer surgeon in OMR can help clarify when and how often tests may be needed.
When Should You See a Colorectal Cancer Surgeon?
Seeing a colorectal cancer surgeon does not always mean surgery is immediately required.
You may be referred to a surgeon if:
- A biopsy confirms colon cancer
- Imaging suggests a tumor that may need removal
- Polyps cannot be safely removed during colonoscopy
- Symptoms are persistent and unexplained
You might be wondering: Is surgery always the first step?
Not always. In many cases, a Colorectal cancer surgeon in OMR will first discuss all available options, including observation or additional tests, before recommending surgery.
Conclusion
Colon cancer can feel overwhelming, but understanding it step by step often reduces fear. Many symptoms are manageable, and early evaluation can open up more treatment options.
If you’re worried about ongoing bowel changes, family history, or test results, consider speaking with a qualified specialist. Consulting a Colorectal cancer surgeon in OMR can help you understand your situation clearly and plan next steps with confidence.
If something doesn’t feel right, seeking medical advice early can make a meaningful difference.
A consultation can offer clarity, reassurance, and guidance tailored to you.
